DETAILED DESCRIPTION

In general, it has been realized that user preferences may vary betweenuses, and that such user preferences may be analyzed over a period oftime. In such an analysis, user preferences may take the form of datapertinent to historical behavior of the user. Since the use of waterrecycling devices, such as showers, often are part of daily routines, apredictive pattern with respect to user preferences may be determined,and a user preference profile may be generated in order to adjust thewater recycling device to the user's preferences. By comparing thepredicted data with actual observed data, user preference profiles canbe updated such that the preferences of the user associated with theuser preference profile can be further predicted with even greateraccuracy.

The present disclosure describes a water recycling device. Initially,some terminology may be defined to provide clarification for thefollowing disclosure.

The term ‘drain’ referred to in the present disclosure is not to begiven the conventional meaning of a drain; a conventional drain is afixture that provides an exit-point for waste water. In the presentdisclosure, the term ‘drain’ may be exchanged for a collectingarrangement, a sensor tank, a recirculation tank, or a floor unit. Theterm ‘drain’ implies a point leading to a e.g. a sewage, but wherein thedrain does in fact not form part of the sewage itself. In particular,the drain may comprise the sensor arrangement or at least part of thesensor arrangement.

Throughout the present disclosure reference is made to “internal data”.Internal data may be data generated by the water recycling device. Forexample, internal data may be data from a sensor arrangement of thewater recycling device. Internal data may comprise data related to a useof the water recycling device, such as a timestamp. Internal data maycomprise data related to a number of operating parameters of the waterrecycling device.

Throughout the present disclosure reference is made to “external data”.External data may be data generated by an external device. Such anexternal device may for example be a smart device, a smart appliance, asmart car, or any other type of external device. Such an external deviceis preferably able to communicate with the external device and/oranother device communicatively couple with the water recycling device.External data may also be generated by other water recycling devicescommunicatively coupled with the water recycling device.

With reference to FIG. 1, a water recycling device 100 is shown. Thewater recycling device 100 comprises an outlet 104 configured to outputwater. The outlet 104 may be a showerhead, a nozzle, or the like. Thewater recycling device further comprises a drain 106 for collecting usedwater output by the outlet 104; a recirculation loop 102 in liquidcommunication with the drain 106 and the outlet 104, the recirculationloop comprising a water treatment arrangement 112 for treating the usedwater. The water recycling device may further comprise a heatingarrangement for heating water in the water recycling device 100. Thewater recycling device further comprises a sensor arrangement configuredto measure a water quality parameter of water in said water recyclingdevice. The water recycling device 100 further comprises an externalwater path 108 in liquid communication with the recirculation loop, theexternal water path 108 being connected to an external water outlet.Water from the external water path 108 may hereafter be referred to asexternal water. The water recycling device 100 may further comprise acirculation pump 110. The circulation pump 110 may provide for at leastpart of a flow of water in the water recycling device 100. A watertreatment arrangement 112 may be placed downstream of the circulationpump 110. The water treatment arrangement 112 may comprise a filterarrangement and/or a UV light treatment arrangement. The water treatmentarrangement 112 may comprise at least one filter, such as a nanofilter,a microfilter, or a nanofilter and a microfilter. The water treatmentarrangement 112 may comprise at least one particle filter and at leastone microbiological filter. The water treatment arrangement 112 maycomprise at least one active substance for reducing harmful effects ofmicroorganisms in water passing the water treatment arrangement 112.Such an active substance may for example be contained within a filtermedia of the filter, and/or be released to the water inside the watertreatment arrangement 112. Water which has been treated by the watertreatment arrangement 112 may hereafter be referred to as treated water.The heating arrangement may comprise a UV light treatment arrangement.The heating arrangement may be combined with the water treatmentarrangement 112.

According to the present disclosure, data indicating an upcoming use ofa water recycling device by a user may be processed in order todetermine a probability of use of the water recycling device by theuser. Such data may be internal data generated by the water recyclingdevice, and/or external data generated by an external device. If theprobability of use exceeds a pre-determined threshold, a number ofoperating parameters of the water recycling device may be adjustedaccording to a user preference profile associated with the user.

The user preference profile may be generated by receiving dataassociated with a number of uses of the water recycling device. Such anumber of uses may span a period of time. A user group may be determinedbased on the data, wherein the user group comprises a number of users.In one example, the user group may be a family, and the number of userscomprises members of the family. The user group may comprise a singleuser. A number of operating parameters of the water recycling device maythen be determined, wherein the number of operating parameters areassociated with at least one use of the water recycling device by atleast one of the number of users. In one example, the water recyclingdevice is installed in a hotel or the like, and each of the number ofusers in the user group may be associated with a user preferenceprofile. The user preference profile may be linked to a booking systemof the hotel. Hereby, during a period of time, it is likely that thewater recycling device is only used by known users, namely users stayingin a room of the hotel where the water recycling device is installed.Thus, a number of user preference profiles can be generated with highaccuracy for the users staying in the room of the hotel where the waterrecycling device is installed.

In this context, it may also be said that a user staying at the hotelmay have used a similar water recycling device installed elsewhere, andthus the user may already be associated with a user preference profile.The user preference profile may in this case be transferred to the waterrecycling device of the hotel, such that the water recycling device ofthe hotel is adjusted according to the preferences of the user. However,in some cases the user may prefer a different use of the water recyclingdevice of the hotel compared to a use of a water recycling deviceinstalled elsewhere. For example, the water recycling device of thehotel may be situated in a warm environment, and thus the user may wanta lower temperature of output water compared to a use of the waterrecycling device installed elsewhere. In this case, the user may beassociated with several user preference profiles, wherein the severaluser preference profiles are connected to a specific water recyclingdevice. The above examples have been described in the context of ahotel, however it is to be understood that similar principles may applyin any other location, such as in public showers or the like.

Initially, for example when the water recycling device has recently beeninstalled, the number of uses may be low, and thus the accuracy of thegenerated user preference profile with respect to true preferences of auser associated with the user preference profile may be low. However, asthe water recycling device is used, the number of uses increases, andthe accuracy of the generated user preference profile may increase.

It may also be possible for a user associated with the user preferenceprofile to directly input preferences into the user preference profile.Such preferences may for example be a preferred flow rate, a preferredtemperature, a preferred time of day to use the water recycling device,a preferred day of the week to use the water recycling device, or thelike. It may also be possible to generate a user preference profile viadata received directly from a user.

Another possibility is to utilize external data generated via otherwater recycling devices. In this case, the user preference profile maybe generated by receiving external data from another water recyclingdevice, wherein the external data is associated with a use of theanother water recycling device by the user associated with the userpreference profile.

It is to be understood that the user preference profile may compriseinternal and or external data. The user preference profile may comprisedata associated with a number of operating parameters of the waterrecycling device. The number of operating parameters may comprise atleast one operating parameter selected from the group consisting of anoutput water temperature, an output flow rate, and an output duration.Output water temperature here refers to a temperature of water output bythe outlet of the water recycling device. Output flow rate here refersto a flow rate of water output by the outlet of the water recyclingdevice. Output duration here refers to a time period wherein water isoutput from the water recycling device. By the term “adjusting” any ofthe number of operating parameters it is to be understood that anadjustment of a part of the water recycling device may be made. Forexample, adjusting the output water temperature may comprise adjusting aheating profile of the heating arrangement, and/or adjusting an intakeof external water from an external water path connected to the waterrecycling device. The adjustment of the number of operating parametersmay be done in such a way that the number of operating parameters varyover time during a period of use of the water recycling device. Forexample, during a use of the water recycling device, the output watertemperature may initially be low, and increase over the period of use ofthe water recycling device.

Referring now to FIG. 2, an example of a system comprising a waterrecycling device 200, a number of external devices 214, 216, 218, 220,and a prediction engine 225, is illustrated. Here, the prediction engine225 receives internal and external data 224, 226, which is processed inorder to determine a probability of use of the water recycling device bya user. However, it is to be understood that a probability of use ispossible to determine solely by processing internal data 224 or externaldata 226. If the probability of use of the water recycling device by theuser exceeds a pre-determined threshold, a user preference profile 222associated with the user may be identified by the prediction engine andsent to the water recycling device from the prediction engine. A numberof operating parameters of the water recycling device may then beadjusted according to the user preference profile associated with theuser.

It may also be possible to store user preference profiles 222 locally inthe water recycling device. In this case, the water recycling device maybe notified of an upcoming use by the user, and a corresponding userpreference profile associated with the user may be identified by thewater recycling device. A number of operating parameters of the waterrecycling device may then be adjusted according to the user preferenceprofile associated with the user.

Referring now to FIG. 3, an example of a number of operating parametersis illustrated. The number of operating parameters illustrated may becomprised in a user preference profile. However, it is worth mentioningthat the user preference profile may comprise additional operatingparameters and/or internal and external data. A flow and temperatureprofile 328, 330 are here illustrating the output flow rate and outputwater temperature over time by the water recycling device during asingle use by a user. As can be seen a number of time intervals 332,334, 336 can be determined. The number of time intervals 332, 334, 336may be determined in relation to any of the flow profiles 328, 330. Thenumber of time intervals may be comprised in the user preference profileassociated with the user. A full duration of the use (all of the numberof time intervals 332, 334, 336) may be comprised in the user preferenceprofile associated with the user.

Referring now to FIG. 4, an example of data indicating an upcoming useof a water recycling device by a user is illustrated. Here, a number ofuses by a first and a second user 438, 439 are shown over a period oftime spanning a number of time quantities 447. Such a time quantity 447may for example be a number of hours, a number of days, or the like. Thefirst and second user may be identified based on historical internaland/or external data. In the illustrated example, a number of uses bythe first user 438 have historically occurred at specific timeintervals. Such time intervals may for example arise if a user uses thewater recycling device once every morning or the like. A probability ofan upcoming use by the first user may in the illustrated example behigh, based on the user preference profile of the first user. In otherwords, since the first user has historically used the water recyclingdevice at a specific time, it is likely that the first user will againuse the water recycling device at the specific time. In this context,the data indicating an upcoming use of the water recycling device by auser may be said to comprise internal data.

Data indicating an upcoming use of the water recycling device may alsocomprise external data. Such external data may for example be calendarentries in a user's calendar. Such calendar entries may indicate towardsor away from a use of the water recycling device by the user, forexample if the user has reserved a room at a hotel located in anothercity, it is unlikely that the water recycling at home will be used.

External data from a smart phone owned by a user may also be received toindicate an upcoming use. For example, if a wake-up alarm of the smartphone is set to 7 AM in the morning, it may indicate an upcoming use ofthe water recycling device in the subsequent hour.

Data indicating an upcoming use by a user may also be received by theuser identifying himself to the water recycling device. For example, thewater recycling device may be equipped with an identification device,such as a fingerprint reader, an RFID reader, a numeral pad, or thelike. The user may thus identify himself to the water recycling devicebefore use. With such an arrangement, it may be likely that the waterrecycling device will be used by the identified user subsequent to anidentification via the identification device by the user. Thus, theprobability of use may be high, and the correct adjustments of the waterrecycling device can be made according to the user preference profile ofthe user.

Further, the water recycling device may be equipped with a Bluetooth™communications device, or similar communications device fulfilling asimilar purpose, such that the user can be identified by his or hermobile phone, or other similar device equipped to communicate with theBluetooth™ communications device, when these two devices arecommunicating, e.g. when the mobile phone of the user is near the waterrecycling device.

The user may also be, in full or in part, identified based on his or herweight by having a weighing device installed in or under the waterrecycling device. In addition, or on its own, the user may beidentified, in full or in part, by his or her length by having one orseveral sensors in the water recycling device.

Each of the number of uses by the first and second user 438, 439 may beassociated with internal and/or external data 440, 442. The internaldata 440 may comprise data relating to a number of operating parametersof the water recycling device during the number of uses.

Referring now to FIG. 5, a user preference profile 550 may be updated tomore accurately reflect a user's preferences. The user preferenceprofile 550 may be updated by receiving user preference feedback 552indicative of a user preference of the user, resulting in an updateduser preference profile 554. The illustrated user preference profile 550and updated user preference profile 554 depicts a temperature profileand an updated temperature profile respectively. In this case, the userpreference feedback 552 may have been received through the user activelyadjusting an output water temperature via an interface of the waterrecycling device, such as a knob. It may also be possible to receiveuser preference feedback 552 via an interface of a smart device, such asa smartphone, wherein the user actively inputs user preference feedback552.

Referring now to FIG. 6, an example of a method for adjusting a waterrecycling device is illustrated in a flow chart diagram. The methodcomprises a step of receiving data 656 indicating an upcoming use of thewater recycling device by a user; a step of processing the data 658 inorder to determine a probability of use of the water recycling device bythe user; and if the probability of use exceeds a pre-determinedthreshold, a step of adjusting 660 a number of operating parameters ofthe water recycling device according to a user preference profileassociated with the user.

Referring now to FIG. 7, an example of a method for generating a userpreference profile for a water recycling device is illustrated in a flowchart diagram. The method comprises a step of receiving data 762associated with a number of uses of the water recycling device;identifying 764 a user group of the water recycling device based on thedata, wherein the user group comprises a number of users; determining766 a number of operating parameters of the water recycling deviceassociated with at least one use of the water recycling device by the atleast one of the number of users; and generating 786 a user preferenceprofile comprising at least part of the number of operating parametersfor the at least one of the number of users.

A user may also indirectly give user preference feedback. Such userpreference feedback may for example be based on observed behavior of theuser. In other words, if the user usually uses the water recyclingdevice on a specific day of the week, but suddenly starts to use thewater recycling device on another day of the week, the user preferenceprofile associated with the user may be updated with user preferencefeedback to reflect that the user now prefers to use the water recyclingdevice on the another day of the week.

The inventive concept has mainly been described above with reference toa few embodiments. However, as is readily appreciated by a personskilled in the art, other embodiments than the ones disclosed above areequally possible within the scope of the inventive concept, as definedby the appended patent claims.
